IMPROVEMENT IN PAPER-RULING MACHINES.

Specification forming part of Letters Patent No. 159,01 S, dated January 26,1875; application iiled December 9, 1874.

To all whom it may concern:

Beit known that I, TYRANNUs F. COLLINS, of Boston, of the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Paper Ruling Machines; and do .hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 is a side elevation, and Fig. 3 a longitudinal section, of a machine embodying my invention.

It is what is termed a double-ruling machine,7 or, in other words, a machine forruling paper first on one side and next on the opposite one while the sheet may be passing once through the machine.

As heretofore constructed, machines of such character have had their ruling mechanisms supported in and by one single frame, in which case a sheet, Whether for being ruled on one or both sides, had to pass through the carrying mechanisms of both sets of ruling-pens. To accomplish the ruling of one side only of a sheet therefore required the whole machine, except one set of the pens, to be in operation, thereby requiring very nearly, if not entirely, the same amount of power and consequent friction and wear and tear for the ruling a sheet on one side as on both sides.

With a machine constructed in accordance with my invention, the upper carrying-cylinder, with its carrying-bands and pens, may be raised and maintained Awholly out of action with the mechanism for effecting the rst ruling of the sheet, and while the latter mechanism may be in operation. When so raised out of action with the mechanism for effecting the Y iirst ruling, the mechanism for effecting the ism for effecting the first ruling of the sheet. The upper frame A rests upon the horizontal bars a c of the frame B, and between two pairs of posts, b b, erected on such bars. Each of the said posts is provided with an arm, c, that is pivoted to the post so as to be capable-of being revolved horizontally thereon, each arm having a shoulder, d, as shown more particularly in Figs. 4 and 5, one of which is a side view and the other a top view of the post and its arm.

When the upper frame is resting directly on the bars c c, the posts e e and boxes f f prevent it from moving ont of place longitudinally ofthe machine, it being kept in place transversely of the machine by the two pairs of posts b b, and it may be held down by turning the arms c around over its lower girts g g. On raising or lifting the frame A upward and resting it on said arms, its cylinder C will be out of contact with the endless apron D of the lower frame, and consequently will not be revolved thereby when it i s in movenient.

The sheet-carry ing mechanism of the lower or main frame B consists not only of an endless apron, D, with its series of carrying and supporting rollers h z' k l m, arranged as shown, but of a series of endless bands, E, and their supporting-rollers n o p, also arranged as represented, the shafts of the two rollers next the shelf F being provided with connectinggears g r.

The lower pen-carrier is shown at G, and the upper one at H. The two series of carrying bands of the cylinder C are represented at s and t. The bands t are supported by rollers u o w, and the bands s, which are the longer ones, are sustained by the rollers x y, all such rollers being arranged as represented.

In ruling a sheet on one side only, it will be discharged from the machine at the end opposite to that at which the shelf F is arranged.

When the machine is in operation each of the pen-carriers is to be provided with a series of ruling-pens and the necessary fountain or ink-holder therefor.

I claiml. In combination with the frame B and the 2. The combination of the posts B and their two ruling and sheet-carrying mechanisms, rotary arms c, with the two separate frames substantially as described, the separate frame A B, provided With sheet ruling and carrying A, supporting the upper of said ruling and mechanisms, substantially as set forth.

carrying mechanisms, and arranged with and TYRANNUS F. COLLINS.

applied to the frame B, essentially in manner Witnesses: to be operated, as and for the purpose spec- R. H. EDDY, iied. S. N. PIPER.
